If you want to bolt on 550+ wheel HP then these are the turbos for you! These monster turbos are a direct bolt on for 3S's and are sure to make you plenty of power! We re-sleeve and weld the inlet of the TD04 compressor housing to fit the huge 19T wheel. By keeping a TD04 frame turbo you will have much quicker boost response then going with a TD05 turbo.

These turbos come with a standard TD04 turbine wheel however if you want to hit the big HP numbers we recommend upgrading to either the TD04L, TD04H, or the biggest, the TD04HL turbine wheel which are available for an additional charge.

The larger turbine wheel is better matched with the large compressor wheel and will hold more boost at higher rpm's but will have slower boost response the standard TD04 wheel at lower RPM's. Typcial gains upgrading from a TD04 turbine wheel to the TD04HL turbine wheel are 30-40 whp and 40-50 wtq.

Polishing of the inlet/outlet on the compressor housing is available for an additional 40 dollars. We also can port the exhaust housings which will increase airflow and decrease backpressure.
